Improvement in galvanic batteries



Pm@ AUG 16 1370 memes EDWIN D. MCCRACKEN, OF NEW YORK,

Letters Patent No. 106,383, dated August I6, i870.

IMPROVEMENT IN GALVANIC BATTERIES.

The Schedule referred to in these Lettera Patent and making pacxt cf the uma.

ot' continuity ot' action of galvanie batteries, and the consequent necessity for ti'equent renewal of the chemicals. The invention is more especially advantageous in its application to what is known as the electropoion battery, but may be applied in connection with batteries of other kinds.

' 1t consists in the combination of two or f more'bab.

tcries, and a switch, which is so arranged relative] y `to them as to allow either of the said batteries toi'tbe brought iato the circuit of the telegraph line or -other apparat-us worked by the battery, the ,other or others being at the same time thrown out ofthe circuit, with their poles open. The switch being operated at regular or suitable, intervals to bring each battery in turn into operation, and the other or others ont of operation, each is, in tnrn,during the suspension of its operation, allowed to recover its strength and activity, while the circuit remains always rn working order.

The switch may he operated by hand or by any suitable automatic or mechanical means, but, for the sake of illustrating my invention, I will describe it in its simplest form, viz., with two batteries and thc switch operated by hand.

A A A and A A' A are two batteries arranged at any convenient distance from each other, and Ahaving their poles connected uit-h separate bimling-screws, a b and af b', Secured in a board, B, the po'ies ot the battcry'A A. A being connected with the screws b, and those of the battery A A' A' with thc screws a' b'f 'Ihe screws a b are connected, by wires, c d, with two met-al buttons, e f, which project above 'the face of the board B, and the scre ws a' b' are connected by wires c ll' with two similar' buttons c' f', the said buttons being ali insulated from each other, and ail so arranged in a row that the two e' f' alternate with the two e f.

C I) are. two metal arms, which are capable .of swinging horizontally on two binding-screws, E E, s ecured in the board B.

With these binding-screws the ends g hof the main, local, or other wirethrough which the batt-cries oper-- ate, are connected.

The arms O D constitute the switch, and they are connectedl together' by a bar, F, of nou-conducting material, to which isatt-ached a knob, G, which Berges as the handle. of the switch.4

The arms C D ot' t-he switch, and the buttouscf and c' f are, respectively, at such distances apart that the said arms may bear one upon the button e, and the other upon the button f, as shown in 'bold outline in iig. i, or one upon the button e'aud theother upon the but-tou f', as shown in dotted outline in iig. 1k in the latter case connecting the battery AA A'with the wire g h, and in the former case connecting the batterv A A A .with the said wire, either battery he ing out ot' connection, with its poles open, while the other is connected. y

0n opposite sides ofA the switch are two stops, i i, to limit its movement to what is necessary to .throw one and the other battery into the circuit of the wire y h. l l

The switch used in my invention may be variously' constructed, and I should consider any device that might be used, however operated, to throw one battery into and another ont of thc circuit, as a switch, or its equivalent. What I claim as my invention, and desire to secure by Letters Patent, is

The combination, in the same electric circuit, 'of' two -or more batteries and a switch, arranged to bring cach battery in turn into and out of the circuit, substantially as and for the purpose herein described. Y
